the situation depends on the language. in C# and F# at least, the user's solution is required to return a list of int by the type signature, while e.g. Java returns a list of objects. there has likely been some translation drift over time, as this is a very old kata

Hi, I replied to your other comment. I see your logical point, though. Would you like to consider re-writing the description? You could leave that posted with a suggestion flag.

hi, here's my take, hope you don't mind:

• their code filters the list by only allowing numbers
• your code filters the list by only not allowing strings

there's no pragmatic difference in this case given the stated input, but to be intentionally pedantic, I will say that if the array happened to contain a 3rd different type, their code would still function properly

hope that helps

Not to be pedantic but the instructions are to exclude strings, not include numbers, no?
